ATOM RECOMBINATION PART I. HALOGEN ATOMS; PART II. SINGLET MOLECULAR OXYGEN.

The research includes an investigation of the complex mechanisms involved in the recombination of certain atoms, halogens and oxygen. Electrical discharge produced the atoms and their concentration was measured as a function of time by a titration procedure and with an isothermal calorimetric atom-detector. Major conclusions resulting from this investigation are 1 Excited oxygen molecules can be prepared with an electrical discharge. Kinetic studies with these species are possible since the concentration of species as a function of time can be measured calorimetrically or spectroscopically. 2 The excited molecules of O2 are formed in an energy disproportionation process. 3 Two molecules of oxygen can combine their energies and emit it as a single photon. The temperature dependence of the rate constant indicates that the emission comes from a colliding pair of molecules. 4 O2 can dissociate ozone. 5 The dissociation of molecular iodine atoms with the oxygen molecule was observed.
